This invention relates to improvements in flue connections for stoves,the invention, as will appear from the following description andaccompanying drawings,- being more specifically directed to and designedas a flue connection for gas ranges having a top cover. for cookingburners.

lhe public demands that kitchen furniture be made more pleasing in apearance grow m increasingly stronger each ay, and to meet these demandsstove designs, particularly gas stove-designs have materially changed inrecent years. The stove or range illustrated in the accompanyingdrawings is an out- .growth of this pubhc demand as it will be seen thata hinged or swinging cover is rovided for the cooking burners to hide tese burners from sight and the present invenprovided a range which is ofmost pleasing appearance in that all burners and utensils are hiddenfrom view and which is one of the objects of the present invention. -v

Another advantage and object which is an outgrowth of the presentinvention is that cooking under this closed top with the resent flueconnection insures that all coo -ng odors are carried .ofi.v H A rangeutilizing the present invention also has the advantage that it will nottend to heat up the kitchen as greatly as do those ranges or stoves ofthe'common and well known type wherein the cooking burners are open andpermit the delivery of heat and odors into the room.

Another object of the invention is the provision of ailue connection soconstructed as to beoperatable with and form a part of a swingingtop'cover or other moving part. c

A still further improvement which is an outgrowth of thepresentinvention is that gases, products of combustion and odorous vapors arecarried ofi'from the range so that there is no possibility of themdiscoloring the walls adjacent to the range.

Other objects, novel features of construction and improved results ofthe invention will appear from the following description andaccompanying dra a 1 In the drawings:

Figure 5 is a fragmentary view in vertical section taken on the line 5-5of Figure 2..

Figures is a fragmentary horizontal sectional view taken on the line 6-6of Figure 1. Figure 7 is a diagrammatic view partly in vertical sectionillustrating the joining or abutting ends of the stationary and movableportions of the flue.

Reference now being had to the drawings in which the preferredembodiment of the present invention is illustrated and wherein the rangeto which the present invention is I applied comprises at one side thecooking and broiling oven A having the usual outlet fiue B having acollar 10 for connection with. an outlet pipe or conduit,

At its opposite end the range base 11, which base is incidentallysupported above the floor by the usual legs 12 is provided with cookingburners l3 fed from a common gas manifold 1e concealed within a housing15 having a closed front wall 16, side or end wall 17, rear wall 18 andclosed at its other side through abutment with one side. of the ovens Ain gas ranges the cookin burners 13 are beneath either a solid cooiingtop or are beneath a cooking top composed of a grid. Ehe presentinvention is applicable to stoves or ranges utilizing either form ofcooking top.

I The cover for the cooking top is designated'at G and in Figure3 of thedrawings it will be seen that it is in its lowered position to close inthe cooking burners 13 and for the purpose of appearance is of a heightsimilar to the difference in height between the burner chamber 15 andthe height of the ovens A so that when the cover is in lowered positionthe cover top 19 is in the same horizontal. plane and level with theoven, top 20, as clearly is illustrated in Figure 2 of the drawings.This'cover is pivotally mounted. ap-

proximatel midway its length and provided with a hen le 21 by which itcan be raised and lowered.

By reference to Figure 4 the position the cover 0 assumes in its raisedor elevated position will be clearly seen and from this figure it willbe apparent that the rear portion of the cover telescopes the burnerchamher as the side wall 22 of the cover parallels the end wall 17 ofthe burner chamber while the top 19 of the cover parallels the back wall18 of the burner chamber.

The cover is provided with a rear wall 23 which is hinged at its upperedge at a plurality of points 24 to the under side of the rear edgeofthe" cover top so that when the cover is in its raised position thiscover back 23 parallels the rear wall 18 of the burner chamber as isclearly illustrated in Figure 4 of the drawings and. by assumingthisvpiosh tion permits the raising of the cover. ion the cover islowered its rear wall 23 falls by gravity into the proper position toclose the rear end of the chamber formed by the cover as is clearlyevident in Figures 2, 3 and 5 of the drawings. I

At the rear of the range the ordinary outlet -fiue B of the ovens isprovided with an extension D to which extension is connected the fiue'Eforming a part of the back wall 23 of the cover. a

As the cover flue E moves with therear wall of the cover it is necessaryto provide a special form of connection betweenthe fines D and E; In Fires 2, 6 and 7the construction which ma es this possible is illustrated.Here it will'be seen that the top 25 of the yon t etapered outer end 27of the rear wall 28 of this flue and that the bottom 29 of the fluevends atthe bottom of the taper 27 or in other wordsis considerablyshorter than the to 25 of theflue. y v The flue is made in the reversemanner. That is to say, its outer wall 30 is tapered as at 31 in areverse direction. to the taper 27 of the outerwall 28 of the flue Dwhile its -bottom-. .32-has an outwardly extending end 33beyond the edge34-of the rear wall 23 of p the cover., The top 35 of the flue stopsshort of the flue;

one anot of the edge 3401? the cover rear wall 23 or in other words isshorter ,than tl1e bottom 33 By reason of the constructiondescribed andillustrated the two fines D and E can ,be swunfiinto and out ofengagement with or in a telescoping manner. It will flueiortion D, hasan extending end 26 hemanner be seen that the extending portion 26 ofthe flue D will act as a stop for the top 3.5 of the flue E as it willoverlap upon the flue E as clearly illustrated in Figure 6 of thedrawing ,while. the extending portion 33 of the bottom-of the flue Ewill overlap-and abut the outer face of the bottom 29 of thefiue D as isalso apparent in Figure 6 of the drawing. The rear wall 30 of the flfu'eE overlaps the rear wall 28ofthe flue D. Thus it will be seen thatthrough these-overlapping enga ements a continuous flue is ovided when te cover is in its lowered or cosed position,

From the foregoing it" will be seen-that there is provided a rangehaving all of the attributes and advantages hereinbefore pointed out andat the same time having as a part of its structure a flue arrangementwhich is necessarily periodicall broken and yet at the same time is ofsuc a structure to permit this. tem orary breaking of the fine in whatwould he termed an automatic manner as there is no necessity for theloosen ing or tightening of bolts, screws orany fastening means. p v

The depth or height of the cover is suficient to form a covered cookingcompartment in that it provides sufficient room, when the cover is inclosed osition, to accommodate cooking vesselsv oi difierent charactersso that cooking can be carried on with the cover without departing fromthe spirited the invention, as for instance on stoves or ranges usingother forms of fuel as a heating me dium. e
